中国西藏那曲市巴青县发生7.0级地震：国家地震灾害四级应急响应启动 灾情正在核查

那曲——据中国地震台网正式测定，北京时间10月22日22时33分，中国西藏自治区那曲市巴青县（北纬32.40度、东经93.79度）发生7.0级地震，震源深度10公里。美国地质调查局（USGS）测得的震级同为7.0级，震中位于那曲市东偏北约191公里处，震源深度18公里，最大烈度VIII度。路透社称，这是2024年1月以来中国境内发生的最强地震，震中距西藏自治区首府拉萨约400公里，当地震感明显。

中国地震台网数据称，震中5公里范围内平均海拔约4864米，周边人口稀少；震中20公里范围内有江切乡、玛如乡等乡镇，拉萨、林芝、昌都等地也有明显震感。据香港媒体报道，巴青县玛如乡有房屋倒塌、墙体受损；另有当地报道称，落石砸坏一辆汽车和公路护栏，并阻断317国道巴青县境内一段道路。截至发稿时，中国官方尚未公布人员伤亡数字，路透社称伤亡与损失情况尚不明确。

地震发生后，中国地震局启动二级应急响应；国务院抗震救灾指挥部办公室、应急管理部启动国家地震灾害四级应急响应，派出工作组赶赴当地。应急管理部部长张成中视频调度当地情况，要求尽快核实灾情，全力做好抢险救援、群众转移安置和震情监测等工作。

美国地质调查局（USGS）的灾情评估系统（PAGER）对人员伤亡风险发出黄色警报、对经济损失发出橙色警报，评估认为本次地震可能造成人员伤亡、重大损失的可能性较高；震中地区建筑以土坯砖和无筋砖结构为主，抗震能力较弱。该局估算，震中一带有数千人经历了剧烈至严重的摇晃，数万人经历了强烈摇晃。

西藏地处印度板块与欧亚板块碰撞带，地震活动频繁。2010年，邻近的青海省玉树藏族自治州发生7.1级地震，造成至少2698人死亡、近300人失踪。

Magnitude 7.0 Earthquake Hits Baqen County in Nagqu, China's Tibet Region: National Emergency Response Launched as Damage Checks Continue

NAGQU — A magnitude 7.0 earthquake struck Baqen County in Nagqu, in China's Tibet Autonomous Region, at 10:33 p.m. Beijing time on Thursday (14:33 GMT), the China Earthquake Networks Center (CENC) said, with a focal depth of 10 kilometers (6.2 miles), at 32.40 degrees north latitude and 93.79 degrees east longitude. The U.S. Geological Survey (USGS) also measured the quake at magnitude 7.0, placing the epicenter about 191 kilometers (119 miles) east-northeast of Nagqu at a depth of 18 kilometers, with a maximum intensity of VIII (severe). Reuters said it was the strongest earthquake to hit China since January 2024; the epicenter is about 400 kilometers from Lhasa, the regional capital, and the tremor was clearly felt in the local area.

CENC data show the average elevation within 5 kilometers of the epicenter is about 4,864 meters, in a sparsely populated area; townships including Gangqie and Maru lie within 20 kilometers of the epicenter, and shaking was also felt in Lhasa, Nyingchi and Qamdo. Hong Kong media reported collapsed buildings and damaged walls in Maru Township in Baqen County, and local reports said rockfalls damaged a car and guardrails and blocked a section of National Highway 317 in the county. As of publication, Chinese authorities had not released casualty figures, and Reuters said it was not immediately known whether there were casualties.

After the quake, the China Earthquake Administration activated a Level-II emergency response, while the office of the State Council's earthquake relief headquarters and the Ministry of Emergency Management activated a national Level-IV earthquake disaster emergency response and dispatched a work team to the area. Emergency Management Minister Zhang Chengzhong directed the response by video link, calling for the damage to be verified as quickly as possible and for rescue, relocation and monitoring work to be carried out in full.

The USGS PAGER assessment system issued a yellow alert for shaking-related fatalities and an orange alert for economic losses, assessing that some casualties are possible and that significant damage is likely; most buildings near the epicenter are adobe block and unreinforced brick structures that are vulnerable to shaking. The agency estimated that several thousand people experienced very strong to severe shaking and tens of thousands felt strong shaking.

Tibet sits on the collision zone between the Indian and Eurasian plates and is prone to powerful earthquakes. In 2010, a magnitude 7.1 earthquake struck Yushu in neighboring Qinghai Province, about 280 kilometers away, killing at least 2,698 people and leaving nearly 300 people missing.
